A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;

x = 1, y = 5.0125

B) The possible solutions of the given equation will be; x = 3.11 or -3.11

C) The solution to p(x) = g(x) is; x = 0 and y = 0

<h3>How to find the solution to simultaneous equations graphically?</h3>

When we are trying to solve two simultaneous equations, there are three methods we can use namely;

1) Elimination Method

2) Substitution Method

3) Graphical Method

Now, we see that we are to use the graphical method from the given graph.

Now, the solution to the given pair of equation will be the coordinates of the points where both graphs intersect.

A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;

x = 1, y = 5.0125

B) The possible solutions of the given equation will be the point where f(x) = 0 which is where the line crosses the x-axis and so we have;

x = 3.11 or -3.11

C) The solution to p(x) = g(x) is the coordinate;

x = 0 and y = 0

Fraction in simplest form
nataly862011 [7]

Answer:

14/15 meters

Step-by-step explanation:

We add each color of fabric to find the total amount of fabric used.

1/3 +3/5

We need to get a common denominator of 15

1/3 *5/5 = 5/15

3/5*3/3 = 9/15

5/15 + 9/15 = 14/15

PLEASE HELP ME ANSWER! im so desperate bro !!

a)13

b) skewed

c) IQR

d)Sam's observation is correct

e)6.17

Step-by-step explanation:

Step 1 :

From the histogram we can infer that

0 to 2 texts has been sent by 1 student

2 to 4 texts has been sent by 3 student

4 to 6 texts has been sent by 4 student

6 to 8 texts has been sent by 4 student

8 to 10 texts has been sent by 5 student

Step 2:

a)

From step 1 , we can see that there are total of 17 students represented by the histogram

Step 3:

b)

This is a skewed histogram because we have all large values of students on the right of the histogram and smaller values on the left of the histogram.

In symmetrical histogram, there would be large values on the center and the smaller values on both sides.

Step 4:

c)

IQR would be better recommendation for this as this is a skewed histogram

Standard deviation would be recommended for a symmetrical histogram

Step 5:

d)

Total number of students is 17

Number of students who text between 8 to 10 messages is 5

Hence the students who text between 8 and 10 messages is 5/17

which is nearly 1/3 rd of the total students.

Hence Sam's observation is correct

Step 6:

e)

Mean amount of the texts = (1 * 3 + 3* 3 + 5*4 +7*4 + 9* 5) /17 = 6.17
